Section 2.5
Conduit and Loom
Conduit must be used to protect the harness cable and cable splices.
NOTICE: |
|
The conduit must not cover any connectors, switches, relays, fuses, or sensors. |
The following guidelines should be used when designing a harness:
NOTICE: |
|
Wires should be sized and cut to near equal length prior to installing conduit. |
- The distance between the back of the connector or other listed devices to the end of the conduit should not exceed:
- 25 mm (1.0 in.) for a single connector/device
- 75 mm (3.0 in.) for multiple connectors/devices
- All cable breakouts and conduit ends must be secured in place with conduit outlet rings or tape.
Criteria for Conduit and Loom:
- Due to the wide variety of operating conditions and environments, it is the responsibility of the OEM to select a conduit that will survive the conditions of the specific applications.
- Flame retardant convoluted polypropylene conduit or equivalent may be used for most installations. Heat retardant nylon conduit or oil, water, acid, fire, and abrasion resistant non-metallic loom conforming to SAE J562A is also acceptable.
Note: If non-metallic loom is used, secure the ends with tightly wrapped nylon straps to prevent unraveling.
- The diameter of conduit should be selected based on the number of wires being protected.
Conduit should cover the wires without binding and without being excessively large.
